Romans 2:20

20.I take what follows,having the form of knowledge, as a reason for the preceding; and it may be thus explained, — “because thou hast the form of knowledge.” For they professed to be the teachers of others, because they seemed to carry in their breasts all the secrets of the law. The word form is put for model (exemplar — pattern); (81) for Paul has adopted μόρφωσιν and not τύπον : but he intended, I think, to point out the conspicuous pomp of their teaching, and what is commonly called display; and it certainly appears that they were destitute of that knowledge which they pretended. But Paul, by indirectly ridiculing the perverted use of the law, intimates, on the other hand, that right knowledge must be sought from the law, in order that the truth may have a solid basis.
